Cov tawv foob npauj npaim valve, tseem hu ua nrov plig plawg valve, hauv qhov raj xa dej los ntawm qhov kev txiav loj thiab cov ntsiab lus cuam tshuam, yog cov qauv yooj yim ntawm cov tswj valve, tab sis kuj tuaj yeem siv rau cov yeeb nkab uas tsis muaj zog nruab nrab mus tswj. Siv dav hauv qhov cub tawg, roj av, ncu pa nkev, roj av hauv nroog, huab cua kub thiab cua txias, tshuaj tua hluav taws xob thiab kev tsim hluav taws xob los tiv thaiv ib puag ncig kev tiv thaiv kom thauj ntau yam xeb, tsis xeb dej nruab nrab cov yeeb nkab.
Thaum txhim kho lub foob siv tawv npauj npaim valve, cov ntsiab lus hauv qab no raug nqi:
Ua ntej, qhov nyuaj ntim npauj npaim valve nyob rau hauv txheej txheem tuav tsis pub kov, yog li kom tsis txhob muaj kev puas tsuaj rau lub sealing;
Thib ob, lub valve tso cai rau txhua txoj haujlwm, kaum sab xis thiab qhib kev teeb tsa;
Thib peb, thaum tsis siv, yuav tsum muab tso rau qhov chaw txias qhuav, lub phaj valve hauv qhib 5 ° ~ 10 ° lub xeev, ob qho kawg ntawm qhov thaiv thiab kom npog;
Thib plaub, lub valve tom qab kev teeb tsa, tus neeg siv tau tuaj yeem teeb tsa kev saib xyuas lub sijhawm raws li qhov qhib thiab kaw zaus, raws li cov cai ntawm lub voj voog, kom ncav sijhawm rau lub koom haum tswj xyuas roj nplua;
Thib tsib, lub pob valve thaum qhib thiab kaw kev cuam tshuam, yuav tsum txheeb xyuas qhov laj thawj ntawm kev cais tawm, yuav tsum tsis txhob siv pob qhov txheej txheem yuam kom qhib thiab kaw;
Thib rau, lub pob hluav taws xob tau teeb tsa nyob rau hauv lub raj xa dej kom paub tseeb tias lub rooj zaum thiab cov yeeb nkab coaxial, thiab hauv ob qhov kawg ntawm qhov flange thiab lub cev valve nruab nrab ntawm cov xuab zeb tsim nyog gasket;
Xya, lub valve yuav tsum tsis txhob txuas rau ntawm cov ces kaum ntawm cov yeeb nkab lossis tom kawg ntawm txoj kab yeeb nkab. Thaum lub valve tau nruab rau hauv nruab nrab ntawm cov yeeb nkab, cov yeeb nkab ntawm ob qhov kawg ntawm lub valve yuav tsum raug kho kom ruaj thiab ruaj khov;
